Description

The LA9511W is a transmitter IC developed for freespace infrared transmission of stereo audio and video signals. It integrates all the required functions for transmission, including audio signal modulation, video signal modulation, LED drive, and other functions on a single chip. An AV coupler system can be implemented easily using this IC and a receiver IC (such as the LA9520V).
